This module provides the students with the opportunity to apply geochemistry and simple experimental systems to an understanding of igneous rock suites and the petrogenesis of igneous rocks on a global scale. Isotopic techniques for magma source identification and age dating are introduced. Metamorphosed rocks are studied in detail to show how the influence of initial rock composition (protolith), fluid migration (metasomatism) and varying temperature and pressure dictate the metamorphic mineral assemblage.
Aims
The module aims to introduce students to the fundamentals of igneous and metamorphic petrology, including and understanding of the importance of mineralogy and rock texture to the interpretation of igneous and metamorphic rocks and an appreciation of the links between petrology/geochemistry and geodynamics (plate tectonics).

Description of Module Assessment
1: Portfolio weighted 50%Practical Assessment (Igneous Petrology)Students submit a portfolio of work completed over the course of the module in the scheduled teaching sessions (combined lecture and practical sessions). This includes five case studies in igneous petrology, which focus on rock description in hand specimen and thin section as well as related exercises covering aspects of magmatic differentiation, phase diagrams, igneous geochemistry and petrogenesis of igneous rocks in a range of plate tectonic settings.
2: Practical Exam weighted 50%Practical Assessment (Metamorphic Petrology)Assessment of practical work in metamorphic petrology based on work completed by the students over the course of the module.
